Blue Hole
This natural round hole rock formation carved out over centuries by the wind and the sea is over 10m/32ft in diameter and is 16m/52ft deep. There is a large window on 7m/22ft below the surface, which enables divers to leave and return from the open sea. On the seabed at the back of the Blue Hole is a cave, which is normally explored at the end of the dive. Along from the Blue Hole is the Chimney, which is a fissure large enough for one diver at a time before it opens up at the depth of around 8m/26ft into an area known as the Coral Garden.
